WILLIAM JOHNSON KENYON, or HIGHLANn PARK, NEW JERSEY, AssreNoR 'ro oHN- soN & JoHNsoN, or NEW BRUNSWICK, NEW JERSEY, A. conceonamro or NEW JERSEY SPUTUM our Application filed. October 3, 1930'. Serial No. 486,244. v

The invention relates to sputum cups of the readily disposable type such as are generally constructed of fiber or the like material in the form of a pouch or pleated pocketbook for convenient disposal or carriage.

Principal objects of the invention are to reduce the cost of manufacture by simplifying the construction; to strengthen or reinforce the major wall elements by overlaps that also are efiective to prevent drainage from the cup; and to provide positive means for securing the article in its final or cup form.

Other objects as well as the nature, chara acteristic features and scope of the invention more readily will be understood from the following detailed description, taken in connection with the accompanying drawings, forming a part hereof, wherein:

Figure 1 is a plan view of a blank for a sputum cup embodying the features of the invention.

Fig. 2 is a perspective view of the improved cup.

Fig. 3 is a vertical section through the side walls.

Fig. 4 is a vertical section through the main walls.

Figs. 5 and 6 are views showing folding op- O erations.

According to the invention there is employed a blank, Fig. 1, consisting of a main body portion 5 of generally square form but with marginal extensions hereinafter referred to, said main body portion being scored or creased to provide lines of folding. The central part of the blank forms the usual flat bottom 6 from which spring major wall sections 7 and 8, and wings 9 and 10. The wings are scored, as indicated, to provide for lines of folding to establish flat side walls 11 flanked by inwardly directed pleats 12.

The respective major wall sections 7 and 8 are formed or provided marginally with rectangular extensions 13 and 14, whereof the one constitutes a flap or closure for the article in its cup state, and whereof the other constitutes an overlap to embrace and retain a pair of pleated wall sections, and is provided so with a slit 15 adapted and arranged to be penetrated by an ear 16 extending marginally from one of said pleated" wall sections and undercut as at 17 A similar overlap 18 extends marginally of the body stru'cturefon the fiap side thereof, that is to say, at right angles to the adjoining side section and has a slit 19' to cooperate with an undercut ear 20 extending from the oppositeside section and catercorner to the first'ear.

In manipulating the blank to reduce itto cup form, opposing major pleats are folded into overlapping engagement upon, forex ample, the flap carrying major wall, the pleat carrying the overlap being in direct contact with said major wall. section so that when the opposing pleat is positioned andits appendage or'ear 20 is made; to penetrate the slit 19, the overlap can be forceddown over said pleats and into the cup thus locking them in their trussed state and this positive form 7 of lock is emphasized by the fact that the ear is undercut so that it cannot accidentally escape from the slit. The same manner of folding applies to the other pair of major pleats so that the folded blank in its ultimate or cup form is characterized by two inwardly directed and confronting overlaps which secure the object in its cup state, operate to arrest drainage, and being inwardly directed with respect to the receptacle or cup, serve to retain the usual cotton or other absorbent filling.

Having described the invention, what is claimed is: l

1. Ablank for forming sputum cups, comprising a substantially rectangular section centrally providing a bottom section and front and rear walls for the cup, the sides of the blank beyond the central wall and bottom provisions being scored for folding to provide collapsible sides for the cup and interfitting sections overlying the front and rear 7 wall sections in the formation of the cup, the

blank including an extension of the front 95.

wall and of the full width thereof for overlying the folded side sections when the cup is formed, one of the side sections of the blank having an extension of the full width of the rear wall section and serving to overlie the 9 2. v p v r 1,850,015

folded side sections bearing against such rear wall When the cup is folded.

2; A sputum cup formed of a single blank having a bottom, front and rear Walls, and.

side sections folded to present cup sides and interfitting sections overlying the inner sides of the front and rear Walls, means integral With the front Wall to overlie and substantially cover the interfitting side sections bearingagainst such Wall for their full Width and V I an appreciable portion of their length, and a fiap' secured to one of the side sections to overlie and cover the upper ends of the interfit ting side sections bearing against the rear Wall said flap covering the upper ends of the interfitting side sections, and being of the full Width of the cup. v

3. A sputum cup formed of a single blank, formedlto provide a -botto1n, front Wall, rear vvall, side walls and'belloWs-fold sections connectingthe front and rear Walls and the side walls, the bellows-fold sections overlying the innersides of the front and rear Walls, the blank having a section integral With the front all to cover the upper ends of the bellowsfold sections bearing against such front Wall, one of-the' bellows-fold sections having a pro-1 jecting portion to overlie and cover the upper ends of such bellows-fold sections bearing against the rear'Wall, both of said covering portions being of'the full Width of the cup.

In testimony whereof I aflix my signature.

WILLIAM JOHNSON KENYON.
